Glass insulator CTV175 U40

Diameter: 175mm

Height: 110mm

creepage distance: 190mm

we ourself produce glass piece with our aobest marking, have three reasons:

1：to avoid no resource for glass piece inmarket，

2： Break the monopoly of the market in short and no goods for glass parts

3: provide competitive price and good quality for clients.
